on your Kibana console are you able to use the _sql endpoint?

POST _sql?format=txt

@NoGroceries @justmike1
I resolved this issue by installing opensearch-sql plugin.
https://docs.opensearch.org/docs/latest/install-and-configure/plugins/

Here is my command for opensearch 2.18.0
opensearch-plugin install https://repo1.maven.org/maven2/org/opensearch/plugin/opensearch-sql-plugin/2.18.0.0/opensearch-sql-plugin-2.18.0.0.zip
